Open Access: Current
Scenario
Status of Open Access
• Electricity Act, 2003 envisages States to implement open
access for 1MW+ customers by Jan, 2009
• IEX pioneered operationalisation of retail open access,
first transaction was in August, 2009
• Several operational and regulatory impediments have led
consumers to choose partial open access and not full
open access
• Consumer maintains its supply agreement with local
distribution company and leverages market for
economical and contingency power.

Cost Economics
for Industries
Open Access Charges: What a consumer pays
PoC charges
• Inter-State Transmission charges payable by the open access consumer
Transmission Charges or STU Charges
• Payable to the state transmission utility for the use of the transmission system for availing
power through open access.
Wheeling charges
• Charge to the Discom for conveyance of electricity through open access as determined by
the SERCs
Cross Subsidy Surcharge
• Subsidising open access consumer has to pay a cross subsidy surcharge to the Discom.
Others
• Additional Charges, if any
• NLDC application fee, scheduling and operating charges, SLDC Charges
• IEX transaction charges/Trading Margin
Open Access: What a consumer pays
Losses
• An open access consumer has to bear in kind the following losses as
defined by the relevant regulations
Point of connection (PoC) loss
• Inter-State transmission system loss
Transmission loss or state loss
• Consumer to absorb apportioned energy losses in the
transmission system as per the relevant regulations
Wheeling loss
• Technical losses in the distribution system determined
at various voltage level by the state commissions.

Assumptions:
- Consumer connected at 33kV level
- Consumer load = 1 MW
- Average Price at which procured from IEX = Rs 2.5/kWh for all
- Calculating landed cost after adding POC, STU & Wheeling Charges & losses,
NLDC operating & application charges, SLDC charges, IEX transaction charges

Cost saving for Industries Procuring Power
through IEX
Case study of some industrial units shows the monthly cost saving as a result
of procuring power from IEX instead of resorting to costly power from DG sets

Barriers to Open
Access
Barriers to Open Access
Prohibitive Open
Access Charges
• High Cross subsidy surcharge
• High wheeling charges
• Additional surcharge
Legislative
Impediments
• Gross misuse of certain statutes in
the EA 2003 (Section 11, Section 37,
Section 108, etc.)
Operational
Hurdles
• Unwilling /Incapable SLDC
• Procedural Bottlenecks
• Physical infrastructural constraints
States allowing open access
• Haryana: High CSS and additional
surcharge of 50 p/unit
• Punjab: High CSS and high
wheeling charges (same for all voltage)
• Gujarat Charges applicable on the
reserved quantum (OA requested) &
additional surcharge of 42p/unit
• Rajasthan- No issue
• Tamil Nadu: OA not allowed to
Sellers, Sec-11 invoked
Restrictive Open Access
•
High Open Access charges:
• Chhattisgarh, Orissa, Assam – High
CSS
• Meghalaya: OA charges for full day
on highest quantum in a time block,
•
Approvals and additional requirements:
• Maharashtra: Power through
Exchange permissible only on week
ahead basis or higher and not on
Day-Ahead basis.
• Himachal : Requires exact schedule
a day in advance for purchase
through Discom
• MP: Approval from Discom
• Karnataka: Imposed Sec 11 briefly.
Consumers OA is possible.
•
Infrastructure Constraints:
• Tripura, Mizoram, Manipur, Nagaland,
J&K
States not allowing open access
• SLDC Hindrance
• Uttar Pradesh, Bihar, Jharkhand Approvals not given
• Absence of adequate regulatory
framework
• Sikkim: Regulatory inadequacy
• Open Access made unviable through
high charges
• West Bengal: High CSS and flat tariff
• Jharkhand: High CSS
•
Delhi: Either Discom or OA
General Issues and resolution
•Financial Settlement
–Delay in Energy Credits (Haryana )
–UI Settlement –
– No credits for under drawals
• NoC for longer periods (3-6m)
• Same NoC applicable for intra-day transactions
–Procedures to be issued by NLDC

Open Access Registry Framework
Proposal for implementation
• This will bring in transparency and
facilitate faster transactions using
automatic rule-based open access
clearance while removing manual
discretions
• Integrated IT based system
• All OA approvals automated
• Function as an interacting medium
between the OA Participants, Trade
Intermediaries/PXs
and
National/Regional and State LDCs.
• Record of Information will be available
to CERC, System Operators, OA
Customers, Traders and PXs
Stakeholders
OA Applicants

Institutions
(in future)
LDCs
Regulators
OAR
• Store information of all OA granted
• Info on inter-state corridor available
for STOA as uploaded by NLDC/RLDC
• Info on availed STOA corridor
Proposed amendment in the Electricity Act, 2003
Separation of Carriage & Content
• Broad Principles
– Distribution and Supply shall be recognized as separate licensed activity
– Distribution Licensee: To be responsible for development, operation and
maintenance of distribution network business and shall have an obligation to
provide connection on demand to any consumer in its area of distribution
– Supply Licensee: Clear unbundling from existing distribution licensee
• Responsible for arranging supply of electricity to all consumers in the
area of supply. The areas of supply for the incumbent supply licensee to
be the same as area of distribution for the distribution licensee
– Competition among suppliers for eligible customers (1MW+)
• We need to deal with India-specific issues
– Cross subsidy elimination Roadmap
– T&D Loss Treatment (Supplier Vs Distributor)
– Exempt small utilities from Unbundling
